This is my cellphone, last time I checked. See this background? I choose it. And the ringtone? From my favorite video game. Oh, the cellphone charm? Yeah, I'd like to see some guy with that one.

So when you call me, don't expect me to hand the phone over to anyone else, because calling my personal cellphone signals that you want to converse with me, not my brother who has a phone of his own. It's rude and downright "What the crap?" when you call to speak to someone else.
